Beschreibung
Zusammenfassung:	A light emitting device includes: a solid-state light emitting element that radiates blue-series laser light; and a wavelength converter 100 that absorbs the laser light and performs wavelength conversion of the absorbed laser light into light with a longer wavelength than a wavelength of the laser light. The wavelength converter includes: a silicate phosphor 1 containing Lu2CaMg2(SiO4)3:Ce3+ as a main component; and an aluminate phosphor 2 containing Lu3(Al1-xGax)2(AlO4)3:Ce3+ (where x is a numeric value that satisfies 0
